Drainage structure for a work vehicle

Abstract

An engine compartment accommodates an engine. A cooling device is configured to cool the engine. A cooling compartment accommodates the cooling device. A division wall is disposed between the engine compartment and the cooling compartment. A ventilation portion includes a hole for permitting air to pass therethrough and is provided on a top surface of the engine compartment. A water receiving member is disposed under the ventilation portion within the engine compartment. A water catchment member is disposed in the cooling compartment and catches water received by the water receiving member. A drainage pathway is connected to the water catchment member and leads the water to a predetermined drainage position.

       5. The work vehicle according to  claim 2 , further comprising
 a partition plate disposed between the engine compartment and the cooling compartment, the partition plate upwardly extending from the bottom plate, 
 the partition plate including a hole for permitting water to pass therethrough when the water flows from the water receiving member to the water catchment member. 
 
     
     
       6. The work vehicle according to  claim 1 , wherein
 the drainage pathway downwardly extends from the water catchment member within the cooling compartment. 
 
     
     
       7. The work vehicle according to  claim 6 , wherein
 the predetermined drainage position is located lower than the engine, and 
 the drainage pathway extends from the water catchment member to the predetermined drainage position through the cooling compartment. 
 
     
     
       8. The work vehicle according to  claim 6 , wherein
 the predetermined drainage position is located away from the division wall in a direction opposite to the engine compartment within the cooling compartment, and 
 the drainage pathway extends from the water catchment member to the predetermined drainage position within the cooling compartment. 
 
     
     
       9. The work vehicle according to  claim 6 , further comprising
 an engine auxiliary machine disposed in the engine compartment, the engine auxiliary machine being located lower than a lower end of the division wall, 
 the predetermined drainage position being located lower than the engine auxiliary machine, and 
 the drainage pathway extending from the water catchment member to the predetermined drainage position through the cooling compartment. 
 
     
     
       10. The work vehicle according to  claim 6 , further comprising
 an engine auxiliary machine disposed in the engine compartment, the engine auxiliary machine being located lower than a lower end of the division wall, 
 the predetermined drainage position being located away from the division pall in a direction opposite to the engine auxiliary machine within the cooling compartment, and 
 the drainage pathway extending from the water catchment member to the predetermined drainage position within the cooling compartment. 
 
     
     
       11. The work vehicle according to  claim 4 , further comprising
 a partition plate disposed between the engine compartment and the cooling compartment, the partition plate upwardly extending from the bottom plate, 
 the partition plate including a hole for permitting water to pass therethrough when the water flows from the water receiving member to the water catchment member. 
 
     
     
       12. The work vehicle according to  claim 11 , wherein
 the drainage pathway downwardly extends from the water catchment member within the cooling compartment. 
 
     
     
       13. The work vehicle according to  claim 12 , wherein
 the predetermined drainage position is located lower than the engine, and 
 the drainage pathway extends from the water catchment member to the predetermined drainage position through the cooling compartment. 
 
     
     
       14. The work vehicle according to  claim 12 , wherein
 the predetermined drainage position is located away from the division wall in a direction opposite to the engine compartment within the cooling compartment, and 
 the drainage pathway extends from the water catchment member to the predetermined drainage position within the cooling compartment. 
 
     
     
       15. The work vehicle according to  claim 12 , further comprising
 an engine auxiliary machine disposed in the engine compartment, the engine auxiliary machine being located lower than a lower end of the division wall,
